The guild is trapped in a parallel world run by an insane king determined to steal every last drop of magic power. When the power-hungry monarch harnesses the power of the Dragon Slayers, he ignites all-out war. But his ambition doesn't stop there: he's heading to the Fiore Kingdom to steal all of its magic as well. Fairy Tail's actions will decide the future of two worlds, but they'll be lucky if they can save even one.
